About Marksy
Clear feedback before the deadline
Why Marksy exists
IB students often wait days for feedback, then receive it when there is barely any time left to edit. Private tutors can help, but many students cannot afford one whenever a deadline gets close.
Marksy gives students another chance to check their own work. It shows an estimated mark, points comments back to the draft, and puts the most important changes first. Its criteria guidance is independently written, and its marks are estimates rather than official results.
What We Do
Grade a draft
Upload an Internal Assessment, Extended Essay, TOK task, or other supported coursework. See an estimated mark, marks by criterion, highlighted comments, and a list of fixes.
Instant Feedback
Get feedback in minutes, not days. You can edit the draft and check another version while the comments are still useful.
More than draft grading
Practise an oral, check sources, read free Physics and Biology chapters, try simulations, and compare IB subject choices.
Our Values
Clear limits
Marksy uses independently written criteria guidance. Its marks are estimates, not official IB results, and may differ after teacher assessment or moderation.
Useful before the deadline
Feedback should arrive while there is still time to change the draft, not after it has already been submitted.
Student-Focused
We write for the student who is stuck, stressed, or unsure what to do next—not only the student chasing a 45.
Transparency
Comments should show where they came from and what they mean. Students keep control of every final change.
